The sound skips or there is noise coming from the speakers.

    IMPORTANT: This article applies only to specific products and/or operating systems. Check Applicable Products and Categories for details.

    Follow these troubleshooting steps in order to see if the issue is resolved:

    1. Set the RF Channel to Off, and then back On: Select SetupAdvanced SettingsSpeaker SettingsWireless Speaker SettingsRF Channel to Off, then set it to On.
      • We recommend you set the RF Channel to On. This allows the Sound Bar to automatically select the best channel for transmission, which makes it stronger against wireless interference.
      • If the sound issue persists, try setting the RF Channel to Off.
      • It may take a minute to reconnect after you change the RF Channel settings.
      • The frequency setting is deleted after disconnecting the power cord. If you disconnect the power cord for some reason, switch RF Channel from Off to On again.
    2. Set the Wireless Playback Quality to Priority on Stable Connection: Select SetupAdvanced SettingsSpeaker SettingsWireless Speaker SettingsWireless Playback Quality, and set it to Priority on Stable Connection.
    3. Set the control box and speakers at a distance of at least 1.5 m (5 ft) from any wireless LAN router (a).
      Note: The issue may also be improved by changing the wireless LAN router antenna’s direction or angle.

    4. If two sides of the speaker are blocked by walls, sound interruptions may happen because of poor speaker communication (See the first image below). 
      Examples 1 to 3 show small adjustments you can make to improve the signal.

      Situation: two sides of the rear speaker are blocked by walls:

      Example 1: Move the speaker more than 5 cm (2 in) away from the side of the wall:

      Example 2: If the speaker can't move away from the side wall, move it more than 10 cm (4 in) away from the rear wall:

      Example 3: If the speaker cannot move away from the corner of the wall, turn it about 45 degrees to create space between the wall:

    5. Check the control box:
      • The control box and speakers might be too far away from each other. Bring them closer together.
      • Remove any obstacles between the control box and speakers, or move the control box and speakers away from those obstacles.
      • Do not install the control box too far back on a shelf. Install the control box in or on a shelf so that the front panel display is not hidden.
      • Move the control box, change the direction of the control box, or install the control box far away from a TV.
    6. Check any wireless devices in the room:
      • If a device that generates electromagnetic radiation is nearby, such as a wireless LAN device or microwave oven, move the speaker system away from that device.
      • Turn off any other wireless LAN devices that are not in use to reduce interference, and then check to see if the issue is resolved.
        Note: If the issue is resolved, change the network connection of the peripheral device from wireless LAN to wired LAN, if possible.
      • Interference between the network connection and speaker connection may occur. Try one of the following:
        • Change the wireless LAN connection of the control box and the router to a wired LAN connection.
        • Switch the band of the wireless LAN router to 2.4 GHz, then set up the wireless network connection between the speaker system and the wireless LAN router again using a 2.4 GHz band.
    7. Reset the speaker system.
      Note: For details on how to reset the speaker system, refer to the Help Guide.
